This invention relates to improvements in in my prior applications for patent for. Hog scrapers, filed May 18, 1906, Serial No. 317,451; Carcass scraping and polishing machines, filed May 29, 1907, Serial No. 365,418; and @arcass scraping and polishing machines, filed July 1, 1907, S9 rial No. 381,815.

in slaughtering establishments as heretotore constructed a large number of men are daily employed in dehairing and polishing the slaughtered animals, such as hogs, and. the number required very greatly increases the ccst of marketing the product. Various machines have from time to time been deshaft with he heaters thereon. an enlarged fragmentary detail showing one. oi the heaters in nian view. I fill As shown in the drawings: A scalding I -l'23il1l-i zia'is provided over and adjecentthe rear end of which is journaled an inclined scraping and polishin r cylinder B, provided with an extension'or oo-t B secured-there 8 0 to, Which scoops the carcasses and scalding Water into the cylinder from the tank, Where the carcasses are acted upon by the intativii heaters within the cylinder. Said tank A as shown, may be of any desired size miss; length ahd is provided with an inwardly inclined end a, shown. J'onrnaled upon suitable frame comprising npright memhers C C', on one side of the tank and 43?, 0X1 the opposite side thereof is the inclined'cvlinder B, the shaft B ofjwhich is vjournalied in suitable hearings on frame members. Said shaft B is provided, as shown, with tight and loose driving pulleys l)'b -l3 whereby said shaft mayhe rotated cell (9.5 preferred, the'direction of rotation thereof reversed by the use of a twist belt driving to one of said pulleys. Said cylinder lsl is journaled on the shaft and the wei ht there of is supported on suitable rollers -5 as shown in Figs. 1 and 2, andin dotted lines in Fi 3, said rolls being jo-urnaled' upon suitable standards which may be either wil nected with, or independent of, the main frame, as preferred, and as shown, iiidicated by h h said cylinder, as shown, being rovided with a flanged circnmfcr entisl and or treclr'b-'b, at a position to track on said rollers'b*b". f I 'Rigidlysecured at the ngore elevated end 119' effective with certain classes of animals frequently operate unsatisfactorily or ineiiithey are termed, and furthermore the high initial cost of such machines and the large expense duction of. the same into use. Furthermore,- such machines have heretofore required considerable space and more or less complicated v mechanism to remove the scalded carcasses from the scalding tank or tub and deliver the same on the finishing bench..

The object of this invention is to provide a Wholly automatically operating machine adapted to be installed in combination with a suitable scalding tank, to automatically remove the carcasses from the tank when the scalding is completed and to deha-ir and polish the same and eventually to deliver when the operation has been completed.

It is a further object of the invention to afiord afconstrnction in which during the entire operation the carcasses are subjected to the action of the scalding WSlilQl" thus preventing the carcasses cooling, and further tinuously rotated.

riveting or in any suitable manner to said cylinder at the more elevated end thereof and. at a point intermediate the end of the cylinder and ring or track I) is a boot or chute B, constructed of metallic plates bent or. formed to the desired shape and affording a boot or scoop 'open on the forward side and which at the extremity curves forwardly, as shown in Fig. 4. Said boot extends at its inner end through the side wall of the cylinder and is of a width toreceive therein the largest carcasses it is desired to scrape or dehair by means of the machine.

As shown, a spring impelled plate or shutter E, is pivotally-engaged transversely of the chute at the inner end thereof and is provided with a pushing spring e, adapted normally to hold said plate extended to partly close the inner end of the chute or boot. Said pushing spring, however, is not sufficiently strong to prevent the plate folding inwardly under the weight of the carcasses passing into the cylinder. One or more stops E, are rigidly secured to the boot or scoop which bears against the outer side of the shutter in its closed position to prevent the shutter being forced outwardly by weightof the carcasses in the cylinder. The cylinder proper is constructed of spirally formed, longitudinal sections or staves indicated by 6. Of these, as shown, the rear edge of the one overlaps the forward edge of the next succeeding, and blocks are riveted or otherwise rigidly secured between the edges, affording a space between the edges of adjacent sections to permit water scooped into the cylinder with the carcasses draining therefrom. As shown also, said tankis extended laterally atfording a semicylindrie casing A partly surrounding the cylinder to the lower end thereof and which inclines downwardly toward the tank to automatically deliver the fluid from the cylinder thereto. As shown also, a head a is provided for said extension of the tank near the middle of the cylinder and this is perforated, to permit the free passage of water back to the tank. As shown, a perforated metallic scraper "A is riveted or bolted to one of the staves of the cylinder and is shaped to fit to the cylindric .extension A of the tank so that as the cylinder rotates, the hair and refuse falling into said extension of the tank is'swerit upwardly by the scraper and delivered? at one side of the machine, the water, of course, passing through said scraper and falling back to the tank. 4

Itigidly secured on the shaft B are more or less flexible beaters constructed, as shown,

of one or more strips or layers of resilient flexible material rigidly secured together and extending transversely of the shaft, and provided with scraping blades on each side of each beater, said resilient arms being indicated as a whole by F, and the oppositely disposed scraping blades by As shown in Fig. 5, three such layers or thicknesses,conveniently of ordinary cotton belting or cotton belting impregnated with rubber, are used. These are bolted on opposite sides of the shaft in pairs, the beater F, being arranged oppositely to the beater F, and the beater F at right angles therewith and arranged oppositely to the beater F and said sets of heaters alternating with the sets arranged at right angles therewith, as shown in Fig. 3. The length of vsaid beaters is such that the ends thereof extend to near the periphery of the cylinder, con veniently into such proximity therewith as to assure the same etl'cctively acting upon the carcasses passing through the c linder. They may, of course, be constructor of any material that will act to some extent centrifugally to strike, beat or scrap the hair and scurf from the carcasses.

At the rear end of the machine, the cyliu der is open or unobstructed, being supported as before described upon the rollers t)-]/ and extending downwardly and outwardly from the rear end is the bench G, upon which the hogs or carcasses slide from the machine.

The operation is as follows: The cylinder beingfdriven in the direction indicated by the arrow in Fig. 4 by means of the sprocket.

wheel D, the carcasses from the scalding tank are scooped up in the boot or scoop B and slide therefrom into the cylinder. As

the same enter the cylinder, the'continued rotation thereof and the projecting ledges formed bythe forwardlydirected edges of the blades forming the successively arranged staves act to continuously roll the carcasses therein subjecting all portions thereof to the action of the boaters F to F inclusive, which thus act to remove all the hair and bristles, the carcasses meanwhile continuing more or less slowly down the inclined eylinder partly by gravity and partly by the rotational action'of the cylinder and the etfect of the heaters.

Ilaving completed the first, rotation, should any carcass be positioned so that it might by, any possibility fall into-the boot B, as the same is directed downwardly, it

is obvious that the only effect would. be in any event to' again elevate the ca. :iss, dc

livering it into the cylinder. Such can casscs, however, can not pass the blade E, which serves as a stop for such outward movement, and the heaters are adapted to act on the carcasses in the mouth of the boot the twist belt from the loose tight pulley b l or on the shutter E, just as effectively as at any other position in the cylinder. As the operation progresses, the hair, bristles, and refuse pass rapidly between the staves into the extension A of the scalding tank. Here, 'with each rotation of the cylinder, the perforated scraping blade A as it passes within said shell engages the hair and bristles and pushes the same up the side of said extension, permitting the water to drain theret-hrough, at last delivering the same from the machine at one side thereof. Should it at any time be desired to reverse the rotation of the beater shaft, this may readily be accomplished as before described by shiftin pulley b to the in which event the straight belt, of course, simultaneously shifts from the tight pulley b to the loose aulleyf If. This instantly reverses the drive 0 'the beaters, thereby enabling the beater to be driven either in the same direction as the cylinder but at a much higher rate of speed, or in the opposite direction of the drive of the cylinder, in which event, of course, the action of the beater assists in rolling the carcasses.

Very many details of construction may be varied. I therefore do not purpose limiting this application for patent otherwise than necessitated by the prior art.
